Benefits of technology

The present invention provides a way to ship riser sections more economically, using a modular system that allows for easy assembly and disassembly. Additionally, the invention allows for easy molding of complex riser sections using a single size mold. Furthermore, the invention eliminates the need for fasteners when connecting individual riser sections.

Problems solved by technology

The problem with the use of these riser sections is they are not stackable or nestable, so that shipping large numbers of these riser sections becomes expensive.

Embodiment Construction

[0052]As used in the present invention, the term “stackable” or “nestable” refers to a structure of similar size and / or configuration, which can fit together in a separable manner; i.e., a series of structures wherein respective ones of said structures can fit into or on respective others of said structures. While, in general, the riser sections of the present invention will have a circular cross-section, it will be appreciated that other tapered stackable configurations could also be used.

[0053]The terms “engagement,”“engagement assembly,”“connection,”“connector assembly,”“connector” or similar words and terms as used herein refer to any formation(s), part, group of parts, whether forming part of the riser sections or separate therefrom, which are useful in connecting the individual riser sections together to form a riser.

[0054]While the present invention will be described with respect to a buried tank forming part of a WWT system, it will be understood that it is not so limited. F...

Abstract

A riser section having a generally tapered, e.g., frustoconical wall, the riser section having a first connector assembly at one end of the riser section and a second connector assembly at the other end of the riser section.

Description

FIELD OF THE INVENTION[0001]The present invention relates to riser sections, risers made therefrom and more particularly, to risers for use in wastewater treatment (WWT) systems or other buried structures.BACKGROUND OF THE INVENTION[0002]In WWT systems such as septic systems, aerobic wastewater treatment systems, etc., the main tank(s) are buried at a desired depth, depending upon the grade of the home or residence using the WWT system and other factors. Accordingly, there is a need in the WWT systems for risers, which extend from the buried tank to slightly above grade to allow access to the tank(s) for periodic cleanout, inspection of air diffusers, etc. Because the tank(s) are buried at different depths, it has been common in the industry to make riser sections; e.g., fiberglass, plastic, concrete, metal, etc. with different lengths. These different length riser sections are then connected in end-to-end relationship to achieve a desired overall length of the riser, which extends ...
